Subject: aacraid and rotational 1 even for ssd disks

Hi.

I wonder if aacraid shouldn't properly inform kernel about sdd disk via 
/sys/devices/../queue/rotational flag?

Using 3.18.22 kernel and aacraid driver tells linux that all drives are 
rotational:

raid:
# cat 
/sys/devices/pci0000:80/0000:80:03.0/0000:81:00.0/host10/target10:0:0/10:0:0:0/block/sda/queue/rotational
1

lvm on top of that raid:
# cat /sys/devices/virtual/block/dm-*/queue/rotational
1
1
1

while this system has raid array of SSD drives only (INTEL SSDSC2BB30). No 
rotational disks.

Adaptec ASR8405 7.8-0 (32730) firmware.
